10028

Encoder not ready to operate (_ecENCODER_NOT_READY)

ABB · ACS850 Standard Program Firmware

What does 10028 mean?

This fault indicates the drive's serial encoder is not providing position data, either because it's still initializing, or its configured resolution doesn't match the drive. This will prevent axis operation, leading to a crash stop and disabling of the axis, posing a risk of uncontrolled motion if not addressed.

Complete Troubleshooting Guide

  1. 1

    Wait several seconds for the encoder to become ready before attempting to enable the axis.

  2. 2

    Verify the encoder resolution configured on the drive is compatible with the physical encoder.

  3. 3

    Connect to the drive with Mint Workbench, navigate to "Parameters > Encoder > Channel 0 > Encoder Parameter(Encoder0, Fault Register)" and check the value. If not 0, refer to the help file for ENCODERPARAMETER for specific guidance.
